Leader in my benchtopTesting these against:#1 MICTUNING C2 LED rock lights ($8+ each) Top rated/very bright heavy wires and housing (but large) tested at 4.5w Not the 24w as advertised but great (not so little) lights. Bought 2 kits. Wont fit everywhere.#2 LEDMIRCY R2 White LED Rock Lights (<$3 each) bright and heavy built, small wires tested at 3.8w#3 SUNPIE White Rock Lights 24 LEDs ($4 each) brighter than most, standard build quality small wires 3.3w - I would not buy again as long as the LEDMIRCY rock lights are at the $3 price point.#4567.... all the rest of the 3/6/9 led (or whatever) rock lights I have all over - all about the same brightness and build quality, nothing great, small wires that are hard to make decent connections to. all <3w power drawNote: I do not have a lumen meter and the lumens/watt ratings are not listed by the manufacturers but the C2 leds seem about 2x light output of all the other rock lights (admittedly cheap ones) I own. If you have the room to mount them and the money, buy the C2s. very heavy wires should make connections much easier. After that, buy the LEDMIRCY R2 for tight spots and decent light output (heck, add these to your cart every once in a while until the price point goes up - i have a few "extra" sets laying about "just in case")
